Improvement in machines for cutting printers  leads



JOHN A. '1. OVEREND, OF SAN FRANCISCO, CALIFORNIA.

IMPROVEMENT IN MACHINES FOR CUTTING PRINTERS LEADS.

Specification forming part of Letters Patent No. 165,859, dated July 20,1875; application filed May 11, 1875.

To all whom it may concern:

Be it known that I, JOHN A. T. OVEREND, of San Francisco city andcounty, State of California, have invented a Device for Cutting PrintersLeads; and I do hereby declare the following description andaccompanying drawings are suflicient to enable any person skilled in theart or science to which it most nearly appertains to make and use mysaid invention without further invention or experiment.

My invention relates to an improved machine for cutting thespacingleadsused by printers into lengths for the different kinds of work, asrequired; and it consists in the employment of an angularlyplaced table,upon which the leads are supported by a slight projection extending backfrom the cutter on one side. Upon the opposite side is an adjustablestop in line with the lead, and this deter mines the length.

The cutter is mounted upon a projecting lug, and operates through a slotin the face of the table,- and as the leads are cut oft they slide downthe inclined face of the table, so as to be out of the way.

The face of the cutter-lever where it moves against the lug ischambered, and this gives the advantage of a rim-bearing, which insuresperfect steadiness, and also a chamber for oil.

Referring to the accompanying drawing for a more complete explanation ofmy invention, Figure 1 is a perspective view of my device. Fig. 2 is asection, showing the manner of mounting the cutterlever. Fig. 3 is aside view of the cutter-lever.

A is the cutting-table, which may be made in any convenient form, butone side of it stands at an incline, as shown. Upon this inclined sidethe leads to be out are placed, and are prevented from sliding olf bymeans of a slightIy-projectin g lug or strip, B, which extends to thepoint where the cutter operates. Beyond this point the face is smooth,so that after the leads are cut off they will slide down and out of theway.

, In order to insure the lead being cut, the face A is made a littlelower-between the cutter and the stop. If made exactly level, the

lead would be bent instead of having a clean cut.

The stop 0 is fitted to the table, and a slot,

D, admits the holding-bolt E, so that, by means of its set-nut F, thestop can be adjusted to any point, and the length of the leaddetermined.

The cuttenlever G is made of the form shown, so as to conform to theshape of the table, and has at its fulcrum end acircular head, H, whichis secured by' a bolt, 1, to the lug J, projecting from the inclinedface of the table A, so that the portion of the lever which carries thecutter K acts nearly vertically upon the inclined face of the table.

The cutter is set so that the upper end will strike the lead a littlebefore the lower end, and by this means the lead will be held firmlyagainst the guiding-strip B, thus insuring the lead being cut straight,and not pushed out of its place in the process of cutting.

A slot is made in the face of the table at L, to allow the cutter topass through, and the edge of this slot may be fitted with a block ofsteel, to serve as the stationary edge of the shears or cutters.

In order to insure a perfect fit between the head H and the lug J,prevent wear, and facilitate lubrication, I chamber either the head orthe lug, as shown at 0, so as to make a circular space around the pin orbolt, and this throws the bearing upon the rim at some distance from thecenter, thus giving steadt ness to the movement of the lever, andpreventing it from rocking. A hole or slot from the upper side allowsoil to be introduced for the purposes of lubrication.

By this construction I am enabled to cut the leads accurately andrapidly, as they re move themselves after being cut, and are certain tohave straight ends. 1 also insure a perfect operation of the cutter andits lever.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

The cutting-table A, provided with an inclined face having twodifi'erent levels, in combination with the longitudinal strip B andadjustable stop C, all constructed to operate substantially as and forthe purpose set forth.
